Have anyone integrated either G SUite (Gmail) add-on to look up CATS profiles within your email or email integration within CATS (see emails sent received from different candidates?) . We are looking to get that developed - so if anyone wants to split costs with us - we can definitely do that.

sending emails from opencats
I've funded a very small enhancement to send emails from contact/candidate pages or the lists for contacts/candidates via the built-in rich-text editor. The body of the email is then recorded to the activity log of each recipient.

receiving emails into opencats
I did have a piece of work on this but it never worked at scale. I understand however that @dveos has developed something separately. Haven't seen it though. You can contact him at info@rekode.co.uk
